I just finished writing a post that is titled "The Star Charts of Apollo."

I have briefly tried to explain how the star charts related to the Apollo Guidance Computer and the Apollo navigation system.

Wow! Very interesting. Thanks for this Larry.

I'm so envious of your collection Larry, you wait til I win the lottery!

Great site though, I learned stuff I didn't know about the charts. I love the AOT chart, I have never seen one of those before.

Spectacular material and a highly educational presentation. Your star chart collection is the first example I know of of a topical collection that tells a story with flown material across the Apollo flights.

While this kind of collection is common in other collecting areas, e.g. postage stamps and covers, I don't think it has been done before with flown memorabilia that was used for a specific purpose on each flight. I think it is a ground breaking collection that will inspire others to try to do the same with other flown material from the Apollo flights.

Now that a reasonable amount of this material has come to market (with more to follow as Aldrin, Cernan and others sell off the rest of their collections), it will be possible to collect based on what these relics were used for on the flights rather than just based on whether they were flown on a flight.

Loved the way you integrated the pix (Great charts, great astronauts, great DSKY), and above all the small serving of Grissom/White/Chaffee legacy, which reminds one of the sacrifices made by some, that others might fly.

Well done, my friend, as this is only one of your many fine collections that you should be quite proud of.

By the way, in case you don't already have as they may go well with this type of collection, I do have an extra Apollo accelerometer, or a Pulsed Integrating Pendulum (PIP), that was made by Sperry Gyroscope Co. in New York for MIT's Instrumentation Labs.

I also have, I think two units, one of the "Apollo II" Inertial Reference Integating Gyros (IRIG) also produced for MIT with part and serial numbers, etc. These were obtained from an Apollo guidance and navigation source back in the early 1980s.

Once again, Larry, thanks for sharing this fabulous collection.

Well done Larry.

What type of plastic was used for the Apollo star charts like this one? Is it teflon?
